## What it means

We validate address format, memo requirements, and rail compatibility at creation time, so an unspendable destination is caught before a user is asked to pay.

## Common causes

* The address is malformed for the given rail.
* The rail requires a memo and none was supplied.
* The asset is not supported on that rail.

## How to resolve

Check the address against the `requires_memo` and format fields for that rail in `GET /rails`. Correct the destination and create a new intent.
